Custom Magnet Assemblies
Bunting-DuBois offers customers turnkey solutions for magnetic assemblies, each designed and built around our core magnets. With all of our projects — from a two-piece assembly to a complex product that demands precision design — Bunting-DuBois strives to meet your exact requirements and complete projects that will reduce cost and develop a repeatable manufacturing process. Plus, we can work with you on your lean manufacturing replenishment program (JIT, Kanban, Dock-to-Stock, etc.) to ensure your parts are always available when you need them.
We are a one-stop shop specializing in custom magnetic assemblies. With our extensive knowledge of CNC machining, magnet fabrication, and final assembly capabilities, we can meet any magnetic assembly need no matter the complexity. We utilize the latest technologies to assembly processes such as bonding, fastening, and potting. Assemblies can be welded, sleeved, or encapsulated. Our final processes (post assembly) include final grind, balancing, magnetizing, and field mapping, allowing Bunting-DuBois to deliver a quality driven and precise magnet assembly no matter the complexity.
Magnet Assemblies
Assemblies made from superior
magnetic materials
Because we manufacture our own compounds for bonded magnet processing and employ a full complement of in-house presses, we are able to give you a precise blend and magnet that will in turn give you the exact shape, strength, complexity and performance you demand — at a cost you can afford.
Sintered Neodymium Iron Boron
Bunting-DuBois Sintered Neodymium Boron magnets offer engineers the ideal combination of low cost and high energy product. We offer a wide range of grades to allow for optimal selection for the magnets’ operating environment.
NeoBlend™ Molded Neodymium Iron Boron
NeoBlend Molded Neodymium Iron Boron (NdFeB) rare earth magnets open up a new realm of possibilities and options for engineers. High magnetic values and reduced size make BREMAG the ideal solution for miniaturization, where weight and space are at a premium.
Injection Molded Ferrite
Bunting-Dubois Injection Molded Ferrite magnets offer design engineers near limitless shape and magnetization possibilities. Its high tensile strength allows injection-molded components to withstand high rotational forces, and it offers both excellent chemical and impact resistance.
Hallbach Arrays
Halbach array assemblies provide a highly controlled, high strength magnetic field. The Halbach array drives many components of modern technology that are essential to our everyday lives. Halbach cylinders, which are magnetized cylinders that produce an intense, contained magnetic field, are used in devices such as magnetic couplings, high field particle focusing cylinders, and brushless motors.
Magnetic Pump Couplings
Magnetic couplings generate a contactless transfer of torque typically used in magnetic drive pumps. The magnets are typically made of rare earth metals, such as samarium or neodymium, alloyed with other metals. The most common combinations are Samarium Cobalt (SmCo) and Neodymium Iron Boron (NeFeB).
Linear Actuators
Linear actuators are incredible devices that convert rotational motion into linear motion, enabling precise and controlled movement in a straight line. At the heart of these efficient and versatile devices lies the ingenious application of magnets. By harnessing the power of magnetism, linear actuators offer exceptional force, accuracy, and reliability in various industries and applications.
Magnetic Couplings
Magnets play a crucial role in magnetic couplings, a sophisticated mechanism used to transmit torque and motion between two rotating components without physical contact. By utilizing the power of magnetism, magnetic couplings offer numerous benefits, including improved efficiency, reduced maintenance, and enhanced safety.
